Subsynchronous resonance (SSR) issue, namely subsynchronous control interaction (SSCI), was observed in doubly-fed induction generators (DFIGs) based wind farms connected to fixed series compensation. This paper proposes a novel scheme to deactivate SSR by adding subsynchronous suppression filters (SSFs) to DFIG converter controllers.

Matrix converter control for DFIG
2013 IEEE International Conference on Emerging & Sustainable Technologies for Power & ICT in a Developing Society (NIGERCON), 2013The matrix converter is made up of a matrix of bidirectional switch elements. The output voltage control is achieved by switching between the allowed switching states using a predetermined sequence. Filters can be used to remove the unwanted high frequency components due to the switching.

An optimal control strategy for DFIG
2010 IEEE International Conference on Industrial Technology, 2010For doubly fed induction machines operating as wind generators (DFIG), the terminal voltage and the active power delivered to the grid are controlled by a PWM converter linked to the machine rotor. The monitoring of the direct and quadrature axis components of the rotor voltage makes possible the control of the terminal voltage and active power ...

New Protection Scheme of DFIGs
2020This chapter proposes a control strategy of doubly fed induction generators (DFIGs) with new protection schemes for enhancing fault ride through capability of wind farms composed of DFIGs and induction generators (IGs). Since the DFIGs will be stressed or overloaded in the process of stabilizing the wind farm during a grid fault, it is paramount to ...

Passivity based control of a DFIG wind turbine
2006 American Control Conference, 2006A novel passivity based control for the electric generator of a wind turbine is presented. Operating points are prescribed to this controller, to maximize generated electric power. The controller is designed using the non-linear model of the electric generator and it is guaranteed to have tracking properties for the electric and mechanical references ...

Sub-synchronous resonance (SSR) occurred in the power system with both Doubly Fed Induction Generators (DFIGs) and series-compensated lines. There have been several papers focusing on the analysis of such SSR phenomenon. To the authors' knowledge, the impacts of DFIG numbers and locations are seldom considered in existing papers.

Study on Transient Characteristic of the DFIG LVRT
Advanced Materials Research, 2013In order to analyze the operational capability of the low voltage ride through ( LVRT) of a gird-connected wind turbine with doubly fed induction generator (DFIG) effectively, it is necessary to evaluate operation characteristics of DFIG under a grid fault.By using the transient principle of the flux of stator and rotor, the expressions of transient ...

Mitigation of harmonics of DFIGs in DC-microgrids
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012During the last few years, there has been an increased attention paid on the developments of DC microgrids (DCMGs) and their applications. For economical and more flexible wind power generation, doubly fed induction generator (DFIG) is regarded as a most commonly used generator in wind farms. This paper presents a configuration and operation method for
